Question

我想使用Eclipse Export功能导出我的Java项目。我的项目包括许多Spring库。我右键单击项目/导出/ JAR文件，选择项目，检查项目的所有内容，指定主类。当我用参数运行它时，会发生错误。如何解决？

更新我试图将其导出为Runnable JAR文件。它显示以下错误。（抱歉，由于安全性，我无法发布整个错误日志）

更新 spring.xml

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="maxActive" value="30" />
        <property name="maxIdle" value="8" />
        <property name="maxWait" value="-1" />
        <property name="validationQuery" value="select version()" />
    </bean>

    <bean id="test" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
        <property name="configLocation">
            <value>ibatis/SqlMapConfig.xml</value>
        </property>
        <property name="dataSource">
            <ref local="dsGlobalRanking" />
        </property>
    </bean>

    <bean id="SomethingDAO"
        class="mypackage.SomethingDAOImpl"
        scope="singleton">
        <constructor-arg>
            <ref bean="test" />
        </constructor-arg>
    </bean>
</beans>

然后我加载它

String contextPath = "classpath:spring.xml";

BeanFactory context = 
    (BeanFactory) new FileSystemXmlApplicationContext(contextPath);

假设您在Jar中有 SqlMapConfig.xml ，例如位置：

/res/ibatis/SqlMapConfig.xml

您应该在 spring.xml 文件中引用它，如下所示：

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
    <property name="configLocation" value="classpath:/res/ibatis/SqlMapConfig.xml"/>
    <property name="dataSource" ref="yourDataSource"/>
</bean>

（注意 classpath：标记）

导出的jar文件不会调整SqlMapConfig.xml
